Milk is flowing through a heat exchanger at a rate of 2000kg/h. he heat exchanger supplies 111,600kJ/h. The outlet temperature of the product is 95C. Determine the inlet temperature of the milk.

The product specific heat is 3.9kJ/(kg*C)

m_dot = 2000 kg/h

q = 111600 kJ/h

T_final = 95C

C_p = 3.9 kJ/(kgC)

equation: q = m_dot*c_p*(T_initial-T_final)

plug in all the value and solve for T_initial

*NOTE* remeber deta_T both in C and K is the same. So don't worry
